Data Transfer Rate Converter

Convert bps, Kbps, Mbps, Gbps and MB/s, GB/s speeds.

?What is the Data Transfer Rate Converter?

A data-transfer-rate converter translates between the way internet speed is advertised (megabits per second, Mbps, Gbps) and the way file downloads actually display progress (megabytes per second, MB/s). This matters because 1 byte = 8 bits, so a '100 Mbps' connection will pull files at only about 12.5 MB/s — a surprise for many users. This tool handles the conversion cleanly so you can estimate realistic download times, compare internet plans, and size network equipment.

The Formula

1 byte = 8 bits. MB/s = Mbps ÷ 8. So 100 Mbps = 12.5 MB/s. 1 Gbps = 125 MB/s.

Bits and bytes are different units. Network gear and service providers advertise in bits per second because hardware signalling is bit-level. File systems and software display progress in bytes per second because files are byte-addressed. Converting between the two is just dividing or multiplying by 8. In real-world use, protocol overhead (TCP/IP headers, retransmissions) eats 5–15% of raw capacity, so a 100 Mbps plan typically delivers 85–95 Mbps of usable throughput.

Practical Examples

1

A 100 Mbps internet plan delivers up to 12.5 MB/s — so a 1 GB file takes at least 80 seconds to download.

2

A 1 Gbps fiber connection moves data at 125 MB/s peak — allowing an 8 GB game update in about one minute.

3

Typical 4G LTE in Pakistan delivers 20–50 Mbps, equal to 2.5–6.25 MB/s — enough for 4K streaming but slow for large downloads.

4

Theoretical 5G peaks near 1 Gbps, but real-world 5G in most cities averages 100–300 Mbps.

5

Old Wi-Fi (802.11n) tops out at 600 Mbps theoretical; real-world throughput at range is usually 50–100 Mbps.

6

A USB 3.0 drive moves data at 5 Gbps (625 MB/s theoretical) — roughly 10× faster than USB 2.0.

Frequently Asked Questions

Because 1 byte = 8 bits. ISPs advertise in bits per second (Mbps); file downloads display in bytes per second (MB/s). Dividing by 8 converts one to the other, and the resulting number is your real 'file speed'.
